Most wanted Avenger to join team in sequel
Scarlet Witch and Quicksilver if indeed they are not licensed off with the X-Men.
I would say Vision, but Vision would require Ultron to be the villain, and clearly that is not the threat they set up in this one. and not to mention, for Ultron you'd need Ant-Man so... yeah...
Black Panther won't be probably appearing due to the... Err "Nature" of the Sequels main villain - so I'll be giving my vote to Ms.Marvels and her (.)(.) She's basically Marvels equivalent to WW and has Alien Space Powers so she'll be easier to incorporate in the movie
Nah, they won't do that since Marvel rea-hea-hea-hea-eally doesn't wanna make "Ant-Man/Giant Man/Wasp/Yellowjacket/any-sort-of-Hank-Pym" solo movie. I think they announced it before Iron Man and it's till going through development Hell. Besides, Marvel knows they have to higher the stakes with the next movie and honestly, Ultron isn't as big of a threat as Mr.Purplechin is.
Now what they're going to IMHO is:
- Try to incorporate the Infinity gauntlet storyline mixed with some small-ish conflict, like return of the Red Skull or such.
- Build up the Gems with each solo movies (like they did with Mandarin rings in Iron Man cartoon)
- Introduce a few new "Spaec Theemd" characters - Maybe Captain Marvel or Kang
Moon Knight would be awesome seeing as how his powers could have stopped Loki a lot quicker, yet you can't ignore the one the only war machine! Although Iron man is the same as War Machine they need more fire power.
My vote is either Moon Knight, War machine, or Black Panther.
